I know that OAI (Polaris/Horizon) uses gas chromatography to measure fuel dilution, they are ISO 17025 certified, and use all of the latest ASTM testing methodologies.I think the OAI one is more accurate. The dipstick smells strongly of fuel when I check the oil. It is consistent with @CarbonSteel ’s results with this engine too.
Does SPEEDiagnostix use gas chromatography or a flame test like Blackstone does? If the latter, given the subjectivity of the results from a flame test, this is why there is such a variation in the results.
